Chelsea captain John Terry is struggling to make their Champions League semifinal second-leg against Atletico Madrid.
The Daily Star says he is rated 50-50 to make a shock return from an ankle injury and face Atletico tomorrow.
It is understood Mourinho is planning to play Branislav Ivanovic at centre back alongside Gary Cahill - with Cesar Azpilicueta and Ashley Cole the full backs - if Terry cannot make it.
